Here's a really lovely papercraft project for Christmas - German paper stars or "froebel stern".
You will need:
Coloured or patterned paper: 4 strips, A4 length and 1cm wide.
It is worth taking the time to cut the paper straight, it makes the project a lot easier!
Rather than make a guide I will point you to the excellent tutorial at craftideas - click here. They have really clear instructions, lots of photos and they have used 4 different coloured papers so that you can see what goes where. There is a good youtube video here if you want to watch them being made.
